SASH FASTENEB 0R LOCK.

Specification of Letters Patent.

Patented Nov. 17, 1908.

To all whom it may concern:

Be it known that I, F RANK Mrs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sash Fasteners or Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to sash fasteners and has for its object to provide a cheap and effective device of this class for securely looking a window in closed position or the sashes thereof in any position relative to each other.

With this and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully de scribed and particularly pointed out in the appended claims.

In the annexed drawing forming a part of this specification in which like reference characters refer to like parts throughout the several views and which are for illustrative purposes only and therefore not drawn to any particular scale, Figure 1 is a side elevation of one form of sash fastener as applied to a window sash; Fig. 2 is a plan view of the same; Fig. 8 is a longitudinal vertical sectional view, Fig. 4 is a transverse vertical sectional view; Fig. 5 is a top plan View with the upper cover removed; Fig. 6 is a perspective view of the bolt; 7 is a top plan view of a modification; Fig. 8 is a bottom plan view with the bottom plate removed; and Fig. 9 is a transverse sectional view.

As shown in Figs. 1 to (3, the invention comprises a sash fastener attached to the upper cross rail of the lower sash 2, of the window. The sash fastener comprises a casing having a lower section 3, and an upper section 4, each section having flanges 5 and 6. The lower flange 5 being slightly recessed as at 7 to receive the upper flange 6. Slidable within said casing is a bolt 8 provided with a middle longitudinal slot 9 adapted to receive screws 10, which pass through the upper and lower sections and into the upper rail 1 serving not only as a guide and limit to the movement of the bolt 8, but also to hold the sections 3 and 4 together, and to hold the casing upon the cross rail 1.

It will be noticed that the extreme distance between the screws 10 is not as great as the length of the slot 9, thus allowing a convenient amount of longitudinal movement of the bolt 8. One end of the bolt 8 is provided with a screw threaded extension 11 projecting through the opening 13 in the casing and on which is mounted in screw threaded engagement the milled-nut 14. The other end of the bolt 8 is provided with a forward extension 15 provided with a laterally extending hook 16 adapted to engage in any one of the notches 17 in the rack 18 secured to the side rail 19 of the upper sash 20, by means of screws 21, in such a manner that the rack 18 projects over the edge of the rail 19 and is received in the notch 22, formed by the extension 15, and the hook 16. Near the outer or screw-threaded end of the bolt 8 is provided a lateral projection 23 between which and the point 25 on the flange 5 is arranged a coiled spring 24. The spring 24 may be either a compression spring adapted to press the bolt 8 outwardly, or may be a retractile spring adapted to draw the bolt 8 inwardly. Either construction has its advantages, and the illustration would necessarily be the same in both cases.

It will be noticed that the bolt 8 together with the projection 23 and the flange 5 forms a casing to hold the spring 24 in place, or if desired a pin 26 may be inserted in the spring 24 to hold the same in place; however, this may be omitted if desired.

The operation of the device is as follows: The milled-nut 14, is screwed back a slight distance to allow the hook 16 to be disengaged from the notch 17 The window sashes may then be moved relative to each other, and when the desired position is found the milled nut 14 may be screwed tightly in place, thus drawing the window sashes together and firmly pressing the rack 18 against the inner end of the casing sections 3 and 4. If the spring 24 is a retractile spring the hook 16 will be automatically disengaged from the rack 17 as the nut 14 is unscrewed; however, if this spring is a compression spring, the hook 16 will normally engage the rack 18.

It will be seen that with this device, the

hook 16 may engage any one of the notches .17, and thus hold the sashes in any desired relative position.

Referring more particularly to the modification shown in Figs. 79, the sash fastener is shown applied to the middle of the upper cross rail 1 of the lower sash and is provided with a substantially triangular casing 27 having a downwardly extending flange 28 passing entirely around the same. The flange 28 is provided with oppositely disposed perforated ears 29 for the reception of screws to hold the casing to the sash rail 1. The upper corner or end of the casing 27 is provided with a downwardly opening outer slot 30 and a pair of inner slots 31 are placed upon the flange of the inner edge of the casingnear the ears 29. Beneath the casing 27 and between the rail 1 is provided a bottom plate 32 adapted to fit within the flange 28 and provided with projections 33 having perforations adapted to register with the perforations of the ears 29. The casing 27, the flange 28 and the bottom plate 32 together form an inclosure 34 adapted to slidably receive the bolt 35 having a pair of forwardly projecting arms 36 having inwardly projecting hooks 37 on the free ends thereof. The outer end of the bolt 35 is provided with a screw-threaded projection 38 adapted to receive the milled nut 39. The inner ends of the arms 36 are connected by a yoke 40 to which said screw 38 is secured. A cross piece 41 connects said arms at an intermediate point and forms a recess 42 through which may be passed a screw 43, said screw passing through a perforation 44 in the casing 27 and being screwed into the rail 1. The screw 43 thus forms a stop to limit the inward movement of the bolt 35.

A. spring 45 is disposed in the casing 27 against the cross piece 41 at one end and against the forward portion of the flange 28 at the opposite end. Guides 46 are placed against the flange 28 to hold in place the inner end of the spring 45, the opposite end being held in place by the converging arms 36. The mid rail 47 of the upper sash is pro vided with a vertical plate 48 provided at the opposite side edges of its inner face with notches 49. These notches are adapted to receive the hooks 37 and when the nut 39 is screwed tight, the hooks 37 together with the cooperating parts securely hold the window against vertical movement. The spring 45 may have its ends secured to the flange 28 and the cross piece 41, if desired, and the same may be adapted to resiliently hold the bolt 35 in either inward or an outward direction, as described of the first form of the invention.

The operation of both forms of'the invention is substantially alike and further description is deemed unnecessary.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is

1. I11 a sash fastener the combination with a rack bar of a casing adapted for attachment to the cross rail of a window sash and having openings at its opposite ends, a bolt arranged in said casing slidable through said openings, said bolt having a longitudinally extending slot arranged intermediately of its ends and being provided with a hook extending laterally in one direction from one end, an arm extending laterally in the opposite direction from the other end, adjustable means mounted on the end adjacent said arm to permit said bolt to be connected and disconnected from said rack bar and a spring arranged in said casing between one end wall thereof and the inner face of the arm.

2. In a sash fastener the combination with a rack bar of a casing open at both ends, a bolt operable in said casing and having a longitudinally extending slot, a hook at one end of said bolt, a screw threaded extension at the other end thereof, a nut operable on said screw threaded end an arm extending laterally from one side of the bolt, spaced fastening devices passing through said cas i11 and slot in said bolt and a coiled spring arranged in said casing between said arm and one end of the casing.

3. In a sash fastener the combination with a rack bar of an open end casing comprising a lower section provided with an upstanding flange, having a groove in the upper edge thereof, an upper section having a depending flange constructed to fit within said groove, a spring pressed bolt operable within said casing having a longitudinally extending slot therein and spaced fastening devices extending through said casing sections and the slot in said bolt to secure said sections together and to form stops for limiting the movement of the bolt.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
